Question

[tex]\mathbb C = \begin{bmatrix} 5 & 4 \\ 2&7\end{bmatrix}[/tex]
1. [tex] \mathbb C^2 = \cdots [/tex]
2. tentukan determian [tex] (\mathbb C^2) [/tex]
..
tambahan rumus :
[tex]\boxed{ \begin{bmatrix} \red a &\red b \\ \orange c&\orange d \end{bmatrix} \times \begin{bmatrix}\green p &\green q \\ \blue r &\blue s \end{bmatrix} = \begin{bmatrix}\red a.\green p+ \red b. \blue r& \red a.\green q +\red b.\blue s\\ \orange c.\green p + \orange d. \blue r& \orange c.\green q + \orange d.\blue s \end{bmatrix}}[/tex]
​

Answer 1

• 

1. 
2. determian

↪ Nomor 1

↪Nomor 2

Det C² = ad - bc

Det C² = (33)(57) - (48)(24)

Det C² = 1.881 - 1.152

Det C² = 729
